Hanzo's Links
Hanzo is Saizo's eldest brother. Hanzo loves his brothers deeply and would do quite possibly anything for either of his brother's.
Saizo looks up to his elder brothers and would do anything for them. While he may have butted heads in the past when Hanzo was trying to keep young Saizo out of trouble, he now appreciates how much the oldest brother cared about his younger siblings. He enjoys any chance he has to hang out with either of his brothers. When his mistress Sumi meets with Hanzo's employer Adelaide, the ninja brothers are still working, but have a chance to enjoy each other's company as well.
Hanzo is employed by Adelaide. They have formed a friendship over his years working for her but it is still a very formal friendship. Hanzo always speaks to and holds Adelaide in the highest regards.
Adelaide employs Hanzo as her Security Specialist. Adelaide views Hanzo as another member of her family in terms of respect and care but their relationship is definitely what many would consider formal. Hanzo respects Adelaide greatly and Adelaide appreciates the security he provides her business, her family, and herself.
